Hi

There are several post about the subject, that you can check

My advice is to narrow the search, since it can be a couple of things

So try to check the usual suspects:

Check stator values
Check spark
Clean carb and check jetting
Check valve clearance

With this simple checks, you can start to have some ideas

That's normal
Let's see if you're cam is pointing up you have some gap between the cam and the actuators
But when you turn the engine the cams will start to push the valves, so no gap
On the next turn you will have gap again
Hope I've made some sense to you

Hi

In one revolution you will have a gap (compression cycle), on the next one you won't have any gap because the valves will be actuated, one the next you will have gap again.

So that gap is what you need to control.

The marks on the cam sprocket are small so you may have to look closer, if you don't have marks do it like the picture

I am I did get to have a look again last night still no good does the decompression leaver need to be forward or back when setting it up as it was not on bike when I got as I don't think I have done it right I have got it pulled back it's like there is to much compression as it keeps flating battery very fast
